SPECIFICATION.

To all whom fit may concern:

Be it known that I, WILLIAM I. TUsTIN, of

i the city and county of San Francisco, State of California, haveinvented an Improved Windmill; and I do hereby declare the followingdescription and accompanying drawing are sufcient to enable any personskilled in the art or science to which it most nearly appertains to makeand use my said invention or improvements without further invention orexperiment.

My invention relatesto a novel device for operating the rudder orguide-vane of a windmill when it is placed in a position parallel withthe wind-wheel. My improvement consists in the employment of a verticalrod which is hinged to the vane-rod or beam, and extends downward eitherwithin reach of a person standing upon the ground, or to a convenientpointalong the length of the vertical beam which supports the wheel, soas to be operated from the ground by means of a lever and cord orequivalent device.

In order to more fully illustrate and explain my invention reference ishad to the accompanying drawing forming a part of this specification, inwhich the figure is a side elevation, showing the rod-connection.

A represents the usual supporting frame. The vertical hollow post B issupported in the cross-timbers C, and passes through the platform D onthe top ofthe frame D. E is the windwheel, which is supported by ahorizontal shaft at the upper end of the swiveling-post B. Theguide-vane F is attached by means of hinges to the cross-beam g upon theupper end of the post B, parallel with the wind-wheel. A rod, h, has itsupper end secured by a loose joint to the beam of the rudder-vane at asuitable point, and extends downward alongside of and parallel with thevertical swivel-post B to near the cross-timber C. To the lower end ofthis rod a ring, i, is secured, which encircles the small lower end ofthe vertical shaft B. A curved lever, j, is pivoted upon one of thecross-timbers, C, so that one end will extend below the ring i, whilethe opposite end extends toward the outside of the frame, and has acord, k, attached to its end, which hangs down within easy reach of aperson standing on the ground.

Now, by pulling upon this cord the lever will be caused to lift the rodh, so as to turn the rudder-vane upon its hinges to a horizontalposition, and thus permit the wind to act upon the wheel 5 and, byreleasing the cord, the rudder-vane will drop by its gravity to avertical position, and thus throw the wheel out of' the winds power.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

In combination with the rudder vane F, hinged as described, I claim thevertical rod h and lever j, or equivalent device, substantially as andfor the purpose above described.

In witness whereof I have hereunto set my hand and seal.
